ABSTRACT
BACKGROUND: Peri-implantitis poses significant challenges in clinical practice, necessitating effective therapeutic strategies. This case report presents a comprehensive treatment approach for managing peri-implantitis, focusing on resective surgery, including implantoplasty and long-term maintenance. METHODS: We describe the case of a 50-year-old female patient with peri-implantitis affecting a maxillary full-arch implant-supported rehabilitation. The treatment strategy involved resective surgery with implantoplasty, a new maxillary overdenture, and a regular maintenance care schedule of three to four visits per year. Clinical and radiographic assessments were performed over a 10-year follow-up period. RESULTS: Post-treatment, all maxillary implants demonstrated no probing depths exceeding 4 mm, absence of bleeding on probing or suppuration, minimal plaque accumulation, and no further bone loss. Resective surgery with implantoplasty seems to have effectively provided submucosal decontamination and created a supra-mucosal implant surface conducive to oral hygiene. Despite regular maintenance, some mandibular implants exhibited bone loss during the follow-up period and were managed using the same approach as for the maxillary implants. CONCLUSIONS: The comprehensive treatment approach yielded favorable long-term clinical and radiographic outcomes, underscoring the effectiveness of the combined strategies in managing peri-implantitis. Nevertheless, the potential for recurrence or the development of peri-implantitis in new implants, even after a decade of successful treatment and strict maintenance, highlights the importance of ongoing, diligent care and regular evaluations to promptly diagnose and address these issues. KEY POINTS: Why is this case new information? The long-term effectiveness of peri-implantitis treatments, particularly involving implantoplasty, remains under-documented. This case provides insights from a 10-year follow-up on the efficacy of a comprehensive approach for managing peri-implantitis. Furthermore, these findings illustrate the potential for new peri-implantitis to develop, regardless of sustained peri-implant health and rigorous maintenance. This finding highlights the critical role of continuous monitoring for the early diagnosis and treatment of new implants exhibiting peri-implantitis. What are the keys to the successful management of this case? The success of this case hinged on a comprehensive treatment approach that combines surgical intervention associated with implantoplasty to remove implant threads, thereby creating smoother surfaces, less retentive for plaque accumulation. A critical aspect of this approach was also the redesign of prosthetic components to improve hygiene accessibility, continuous monitoring, and consistent maintenance care. What are the primary limitations to success in this case? The primary challenge in achieving success in this case was the prevention of new implants with peri-implantitis, despite the patient's consistent adherence to the maintenance program. Moreover, a critical evaluation of implant characteristics, particularly their susceptibility to mechanical failures, is paramount when performing implantoplasty. Furthermore, aligning patient expectations with the realistic esthetic and functional outcomes of the treatment is often challenging. PLAIN LANGUAGE SUMMARY: Peri-implantitis, an inflammatory disease affecting dental implants, is quite challenging to treat. This case report describes how a 50-year-old woman with this condition was successfully treated and maintained over 10 years. The approach included a surgical method called resective surgery, which involved reshaping the bone defect (osteoplasty) and smoothing the implant surface (implantoplasty). Additionally, she was fitted with a new upper denture and had regular follow-up visits three to four times a year. After ten years, her upper implants were stable with no signs of infection or further bone loss, and they were easy to keep clean. Some of her lower implants did experience inflammation with progressive bone loss during this time, but they were managed using the same surgical procedure as for her upper implants. This 10-year case report highlights positive and stable clinical results after resective surgery for treating peri-implantitis and the importance of an interdisciplinary approach and regular check-ups for maintenance, early diagnosis, and management of peri-implantitis over the long term.
ABSTRACT
OBJECTIVE: To digitally evaluate the three-dimensional (3D) remodelling of FGG used to treat RT2 gingival recessions and lack of keratinized tissue on mandibular incisor teeth. METHODS: Data from 45 patients included in a previous multicentric RCT were analyzed. Silicone impressions were taken before (baseline) and 3, 6 and 12 months after standardized FGG placement. Casts were scanned and images were superimposed, using digital software, to obtain measurements of estimated soft tissue thickness (eTT; 1, 3, and 5 mm apical to baseline gingival margin). In addition, soft tissue volume (STV) and creeping attachment (CA) were assessed. RESULTS: All patients exhibited postoperative eTT and STV increases, at all time points. The greatest mean thickness gain was observed at eTT3 (1.0 ± 0.4 mm) at 12 months. At 12 months, STV was 52.3 ± 21.1 mm3, without relevant changes compared to the 3- and 6-month follow-up. CA, which was observed as early as six months postoperatively, was evident in â¼85 % of teeth at 12 months. CONCLUSIONS: Application of FGG was an effective phenotype modification therapy, as shown by the significantly increased tissue thickness postoperatively. Despite the use of FGG technique not aiming for root coverage, digital 3D assessment documented the early and frequent postoperative occurrence of CA, which helped improve recession treatment outcomes. CLINICAL SIGNIFICANCE: The use of 3D assessment methodology allows precise identification of the tissue gain obtained with FGG, which, regardless of technique, results in predictable phenotype modification and frequent occurrence of creeping attachment.

This prospective case series aimed to evaluate the feasibility of using a volume collagen matrix for soft tissue augmentation to increase mucosal thickness in single implants in smokers who consume more than 10 cigarettes per day. Participants had single submerged implants necessitating soft tissue thickening. Soft tissue augmentation was done using a collagen matrix in the second-stage surgery. The primary outcome was soft tissue thickness at 90 days post-surgery. Secondary outcomes included median thickness at 30 and 60 days, changes in buccal soft tissue profile (digital measurements) at 30, 60, and 90 days, and oral health-related quality of life using OHIP-14 up to 90 days post-surgery. Pain levels via VAS scale and adverse effects were also assessed. Ten participants (4 men, 6 women) aged 45.2 ± 13.18 years initially smoked 10-20 cigarettes daily (average: 14.70 ± 3.47 cigarettes/day). After 90 days, median soft tissue thickness increased to 3.00 (2.00;3.00) mm. Buccal soft tissue profile (median change in ROI) increased by 0.40 (0.25;0.62) mm at 90 days. Pain levels decreased, and oral health-related quality of life improved significantly. No complications were reported. The collagen matrix significantly augmented buccal soft tissue thickness at implant sites in smokers (>10 cigarettes/day), with favorable outcomes and no complications.
ABSTRACT
BACKGROUND: The aim of this study was to evaluate the incidence of preloading crestal bone loss (PLCBL) and to identify the patient-related and implant-related factors associated with PLCBL. METHODS: This retrospective cohort examined the dental records of patients who received at least one dental implant. PLCBL was defined as a reduction ⩾0.5 mm and severe PLCBL (primary variable) as a reduction ⩾1.5 mm in mesial and/or distal bone level, measured from the day of implant placement to uncovering or abutment installation/crown delivery. The incidence of PLCBL and patient and implant variables were recorded. Bivariate analysis and binary logistic regression identified factors associated with PLCBL ⩾0.5 mm and ⩾1.5 mm. RESULTS: A total of 746 dental implants placed in 361 patients from January 2011 to July 2021 was included in the analyses. Of the implants assessed, 24.4% (n = 182) exhibited PLCBL ⩾ 0.5 mm and 10.5% (n = 78) presented severe PLCBL (i.e., ⩾1.5 mm). Males (odds ratio [OR] = 1.85, 95% confidence interval [CI] = 1.11-3.07), patients with diabetes (OR = 3.33, 95% CI = 1.73-6.42), and those allergic to penicillin (OR = 3.13, 95% CI = 1.57-6.22) were more likely to experience severe PLCBL (p < 0.05). Implants placed in the anterior area (OR = 2.08, 95% CI = 1.16-3.73), with bone-level platform-abutment connection (OR = 4.73, 95% CI = 1.94-11.49) and inserted supracrestally (OR = 3.77, 95% CI = 1.84-7.72), presented a greater risk of developing severe PLCBL (p < 0.05). Implants placed in a previously grafted area presented a lower likelihood of developing severe PLCBL (OR = 0.489, 95% CI = 0.28-0.84). CONCLUSION: The incidence of PLCBL ⩾ 0.5 mm and ⩾1.5 mm was 24.4% and 10.5%, respectively. Male sex, diabetes, allergy to penicillin, anterior location, bone-level platform-abutment connection, and supracrestal implant placement are potential risk factors for severe PLCBL. A previously grafted area is a potential protective factor.
ABSTRACT
OBJECTIVES: To evaluate the potential of laser-microtextured abutments (LMAs) compared to machined abutments (MAs) in peri-implant clinical and radiographic outcomes. MATERIALS AND METHODS: Eligible studies consisted of randomized clinical trials (RCTs) retrieved from MEDLINE, Web of Science, Scopus, and Embase databases. The study adhered to the PRISMA statement, and the protocol was registered at the PROSPERO (registration number CRD42023443112). The risk of bias was evaluated according to version 2 of the Cochrane risk of bias tool (RoB 2). Meta-analyses were performed using random effect models. Afterward, the GRADE approach was used to determine the certainty of evidence. RESULTS: Four RCTs were included from a total of 2,876 studies. LMAs had lower peri-implant sulcus depth at 6-8 weeks (WMD: -0.69 mm; 95% CI: -0.97, -0.40; p = 0.15, I2 = 53%) and at one year (WMD: -0.75 mm; 95% CI: -1.41, -0.09; p = 0.09, I2 = 65%), but the certainty of evidence was low. In addition, the marginal bone loss favored the LMAs group (WMD: -0.29 mm; 95% CI: -0.36, -0.21; p = 0.69, I2 = 0%) with moderate evidence. There were fewer sites with bleeding on probing in the LMAs group (WMD: -1.10; 95% CI: -1.43, -0.77; p = 0.88, i2 = 0%). There was no statistical difference between groups for the modified gingival index and modified plaque index. Furthermore, all studies were classified as having some concerns risk of bias. CONCLUSIONS: There was low to moderate certainty evidence that LMAs can favor peri-implant clinical and radiographic parameters compared to MAs. CLINICAL RELEVANCE: Laser-microtextured abutments may benefit peri-implant clinical and radiographic outcomes.

OBJECTIVE: This systematic review aimed to compare periodontal outcomes of surgically exposed and orthodontically aligned buccally impacted maxillary canines to spontaneously erupted maxillary canines. DATA SOURCES: An unrestricted search was carried out of indexed databases (Medline, EMBASE, Web of Science and Scopus), reference lists of included studies, and grey literature published until December 2023. DATA SELECTION: Observational and experimental studies that addressed the focused question 'Do periodontal outcomes of buccally impacted maxillary canines that were surgically exposed and subsequently extruded and aligned using orthodontic alignment differ from those of spontaneously erupted maxillary canines?' were included. DATA EXTRACTION: Study screening, selection and data extraction were performed independently by two authors, with disagreement resolved by a third reviewer. The risk of bias was assessed using the JBI Critical Appraisal Checklist and GRADE approach. RESULTS: A total of 857 citations were found and five studies were eligible for inclusion. Supragingival plaque accumulation and gingival inflammation were similar between impacted canines and their contralaterals in most studies. Meta-analyses revealed no significant differences in keratinised tissue width (prospective studies: MD = -0.28, 95% confidence interval [CI] = -1.13-0.56, I² = 78%; retrospective studies: MD = 0.61, 95% CI = -1.51-2.72, I² = 94%). However, a meta-analysis of prospective studies showed slightly greater mean probing depth for impacted canines compared to their contralateral canines (prospective studies: MD = 0.16, 95% CI = 0.04-0.28, I² = 0%). The evidence certainty for keratinised tissue width and probing depth outcomes was low. CONCLUSION: Surgically exposed and orthodontically aligned buccally impacted canines have slightly greater probing depths, potential bone loss and increased clinical crown length, compared to their counterparts. However, these small differences (<1 mm) are unlikely to be clinically significant.
ABSTRACT
Selective outcome reporting (SOR) can threaten the validity of results found in clinical trials. Some studies in the literature have analyzed SOR in dentistry, but there is no study that has observed SOR in clinical trials in oral and maxillofacial surgery. Impacted third molar surgery is one of the most used models in clinical trials to study mainly analgesic and anti-inflammatory drug interventions. Our study aimed to evaluate the prevalence of SOR in publications employing the third molar extraction clinical trial model, and to verify whether there was an association between the statistical significance of outcomes and other characteristics that could lead to SOR. A systematic search was performed on the ClinicialTrials.gov platform for randomized clinical trial protocols, using the condition of third molar extraction. The corresponding published articles were sourced in PubMed, Scopus, and Embase databases, and compared with the registered protocols regarding the methodological data, in terms of: sample calculation, primary outcome identification, end-point periods, insertion of new outcomes in the publication, and results of outcomes. 358 protocol records were retrieved; 87 presented their corresponding articles. SOR was identified in 28.74% of the publications, and had a significant relationship with changes in the protocol, insertions of new outcomes, and discrepancies in the types of study. General risk of bias was found to be low. There were associations between SOR and the discrepancies in terms of the type of study, the choice of new outcome, and changes in the history of protocol records. The prevalence of SOR in clinical research using the third molar extraction surgery model is moderate. The quality of the scientific reporting of the results and, consequently, the certainty of evidence relating to the intervention tested can be overstated, increasing the chances of misinterpretation by health professionals.

OBJECTIVES: This randomized, controlled, double-blinded clinical trial aimed to evaluate the efficacy of octenidine hydrochloride and chlorhexidine mouthwashes as adjuncts to instrumentation in stage I-II periodontitis patients. METHODS: Forty-five patients with mild-to-moderate periodontitis were randomly allocated to three groups: 0.1% octenidine dihydrochloride (OCT), placebo, and 0.12% chlorhexidine (CHX) mouthwashes. Patients were instructed to use the mouthwash after instrumentation for twice a day up to 3 weeks. Periodontal parameters such as probing pocket depth (PPD), clinical attachment loss (CAL), O'Leary plaque index (PI), Loe and Silness gingival index (GI), Lobene stain index (SI), and oral soft tissue changes were recorded at baseline and once every week for 3 weeks. The visual analogue scale (VAS) was also recorded as a self-administered questionnaire at the end of the study. The one-way ANOVA was used to compare VAS scores between the groups. The repeated measures ANOVA and post hoc Newman-Keuls tests were used to assess the differences in the periodontal parameters between groups at different time intervals. The Kruskal-Wallis test was used to compare the mean SI. RESULTS: There was a significant reduction in the mean GI of the OCT and CHX groups compared to placebo (p < 0.05). OCT usage resulted in significantly less staining, according to mean SI, when compared to CHX. Furthermore, VAS scores revealed that OCT was significantly the preferred mouthwash (p < 0.01). CONCLUSION: Adjunctive octenidine hydrochloride may be an alternative to chlorhexidine in its ability to control the periodontal parameters in patients with stage I-II periodontitis. Further larger studies are necessary to confirm these findings.
ABSTRACT
This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother's schooling and malocclusion were associated with the number of sextants with bleeding. The mother's schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

BACKGROUND AND OBJECTIVE: As elsewhere in the world, the prevalence of periodontitis in stages I-II is high in the Latin American population, this scenario emphasizes the need for identification of urgent needs for allocating adequate resources to provide diagnosis, prevention, and treatment of these diseases. The aim of this Delphi study was to predict the trends in periodontology/periodontics in the Latin American region by the year 2030. METHODS: A steering committee and an advisory group of experts in periodontology/periodontics were selected from 16 countries. An open questionnaire of 60 questions was validated and used following the Delphi methodology. RESULTS: Two hundred and twenty-five experts from Latin America answered the two rounds of the questionnaire. Moderate to strong consensus was reached on 45 questions (75%). The prediction was that the prevalence of gingivitis and periodontitis in stages I and II will be maintained, the importance of the link with systemic diseases will increase, and the impact of prevention and periodontal treatment will also increase, mainly in the private sector. There was a strong consensus that plastic and regenerative surgical procedures will increase, as well as the demand for training in the specialty of periodontology. CONCLUSIONS: The present study has provided relevant and useful information on predictions in periodontology/periodontics in Latin America, with important level of consensus among experts. It has been predicted that periodontitis will still be a highly prevalent disease, and its links with other medical conditions should demand more attention by health authorities to develop adequate prevention and management policies and strategies.

ABSTRACT
The Internet is a growing source of knowledge and can provide information about oral health. This ecological study aimed to characterize the interests in toothpaste among Google users from different countries. Our hypothesis was that there would be an increase in Google users' interest in information about toothpaste. This retrospective longitudinal ecological study analyzed the toothpaste-related interest of Google users from 10 countries between January 2004 and December 2020. The monthly variation in relative search volume (RSV) and the main related queries were determined using Google Trends. Autoregressive integrated moving average (ARIMA) forecasting models were built to establish the predictive RSV values for toothpaste for an additional 12 months. Autocorrelation plots and the generalized additive model (GAM) were used to diagnose trends and seasonality in RSV curves. Additionally, the influence of social isolation related to the outbreak of COVID-19 was analyzed. Although not detected by autocorrelation function (ACF) and partial autocorrelation function (PACF) analyses, the heuristic analysis showed an increase in the interest in toothpaste-related information in all countries, with a stable trend observed in the 12-month forecasts, except for the increases in the United Kingdom and South Africa. Also, GAM analyses demonstrated a non-significant monthly or quarterly seasonal influence on data. In addition, social isolation during the COVID-19 pandemic did not influence the online information-seeking behavior of Google Search users linked to this topic. We confirmed the hypothesis that the interest of Google Search users in information about toothpaste increased in all of the 10 assessed countries.

Abstract The purpose of this study was to compare the outcomes of a modified gingival graft technique, in which the released flap is positioned and sutured over the graft, with the conventional free gingival graft (FGG) procedure, when both are used for gingival augmentation. A 12-month, multicenter parallel randomized controlled trial was conducted. Subjects with buccal RT2 gingival recessions and keratinized tissue width (KTW) < 2 mm in at least one mandibular incisor were randomized to control group (n = 20; conventional FGG) or test group (n = 20; modified FGG; flap sutured over FGG using sling sutures). The primary outcome (KTW) was measured at baseline and after 3, 6 and 12 months, as was keratinized tissue thickness (KTT). Postoperative pain (POP) and analgesic intake were also recorded. Both techniques promoted a significant increase in KTW and KTT when compared to baseline (p < 0.05) with no significant differences between groups (KTW change of 6.1±1.5 mm and 5.4±1.6 mm, for control and test, respectively; p=0.16). However, test group patients reported less POP after 7 days and used less analgesic medication than control group patients (p < 0.05). We concluded that the modified FGG was comparable to conventional FGG in augmenting keratinized tissue width and thickness at mandibular incisors, but resulted in less patient morbidity.
ABSTRACT
Abstract The aim of this systematic review was to evaluate the methodological quality and the consistency of recommendations of clinical practice guidelines (CPGs) in Periodontology. An electronic search was conducted in two databases, MEDLINE and EMBASE, eight CPGs databases, and home pages of scientific societies in Periodontology up to April 2022. Three reviewers independently assessed methodological quality using the AGREE II instrument. In addition, we evaluated the consistency of the recommendations. Eleven CPGs were included, and the topics developed focused on prevention, diagnosis, risk factors, surgical and non-surgical periodontal treatment, antimicrobial therapy, root coverage, and maintenance. We found that the AGREE domains 2 (Stakeholder involvement) and 5 (Applicability) obtained the lowest scores. Domains 1 (Scope and purpose), 3 (Rigor of development) and 4 (Clarity of presentation) obtained the highest scores among the evaluated CPGs. The clinical recommendations for treatment of periodontal diseases were mostly consistent. Overall, the quality of CPGs used in periodontics was high. There was consistency of recommendations in specific fields. These findings may help researchers to promote CPGs focused on different fields of periodontics that have not yet been developed. Furthermore, the clinician will be able to make better clinical decisions.
ABSTRACT
Abstract Accumulated evidence has shown that the oral cavity may be an important reservoir for SARS-CoV-2. Some authors have suggested that the use of mouthrinses could reduce SARS-CoV-2 viral load in the saliva. Thus, the aim of this review was to synthesize evidence about the efficacy of mouthrinses in reducing the salivary viral load of SARS-CoV-2. 2. Nine randomized controlled trials (RCTs) have investigated the efficacy of different mouthrinses in reducing salivary SARS-CoV-2 loads. Various active ingredients have been tested in these trials: 0.5%,1% and 2% povidone-iodine, 0.2% and 0.12% chlorhexidine (CHX), 0.075% cetylpyridinium chloride (CPC), 0.075% CPC with Zinc lactate, 1% and 1.5% hydrogen peroxide (HP), 1.5% HP + 0.12% CHX and ß-cyclodextrin and citrox. The studies reported an intra-group reduction in the salivary levels of the virus, when compared with the baseline. However, the majority of these trials failed to demonstrate a significant inter-group difference between active groups and the control group relative to the decrease in salivary SARS-CoV-2 loads. Although promising, these results should be confirmed by larger trials.

ABSTRACT
Abstract The aim of this cross-sectional study was to assess whether favorable factors related to school characteristics have a positive effect on the impact of traumatic dental injury (TDI) on oral health-related quality of life (OHRQoL). An epidemiological survey of oral health was conducted with 12-year-old schoolchildren from Quito, Ecuador. Children were examined for TDI, dental caries, and malocclusion. Individual socioeconomic data were also collected. Information on the physical environment, health practices, and occurrence of negative episodes at school was collected from the school coordinators. The Child Perceptions Questionnaire 11-14 (CPQ11-14) was used to evaluate the OHRQoL (outcome variable). Multilevel Poisson regression analysis was conducted. Severe TDI was associated with higher CPQ11-14 scores, even in the multiple model adjusted for oral health conditions, sex, individual socioeconomic variables, and school-related variables. Children from schools that had an appropriate tooth-brushing environment for their students exhibited a lower impact on OHRQoL, even after adjustment for the occurrence of TDI and other variables. A favorable school environment may exert a positive effect on OHRQoL, independent of the occurrence of TDI.
ABSTRACT
Abstract Objective: This study assessed the efficacy of two adjunct therapies (antibiotic and probiotic) for periodontal treatment based on clinical and immunological parameters in patients with Stage II and III Grade B periodontitis. Methodology: 45 patients were randomly allocated into three groups: control group (CG); antibiotic group (GAtb), in which 500 mg amoxicillin + 400 mg metronidazole were used; and probiotic group (GProb), for which Lactobacillus reuteri was used. Patients received medications after undergoing periodontal debridement. Clinical and immunological parameters were assessed at baseline, 30 days, and 90 days. Results: All therapies reduced bleeding on probing (BoP) in the evaluated periods, and the GAtb had a greater reduction at 90 days (p=0.03). The GProb group showed better results for plaque index (PI) and gingival recession (GR) compared to the GAtb at 90 days (p=0.0014; p=0.006). The area of inflammation (PISA Index) significantly decreased in all therapies in the evaluated periods. Therapies had no significant differences regarding moderate pockets. The GAtb had a greater reduction in probing depth (PD) for deep pockets (p=0.03) at 90 days and in the number of deep pocket sites at 30 days (p=0.04). The occurrence of adverse effects was commonly reported in the GAtb as a percentage per patient. The GAtb had a significant reduction in the concentration of interleukins IL-1β and IL-8 and an increase in IL-10 and TNF-α. The CG had a reduction in IL-6 and IL-1 β, whereas in the GProb there was no difference. Conclusion: After three months, none of the adjuvant therapies provided any additional benefit for subgingival instrumentation.
ABSTRACT
El tabaquismo es un importante factor de riesgo para las enfermedades periodontales y periimplantares. Los fumadores tienen más posibilidades de presentar pérdida de dientes e implantes y puede promover un impacto negativo en la calidad de vida relacionada a la salud bucal (QVRSB). Este estudio prospectivo tiene como objetivo verificar el impacto de la cesación de tabaquismo sobre la QVRSB de pacientes fumadores que recibieron implantes oseointegrados. Todos los participantes recibieron terapia antitabáquica y rehabilitación protética implantosoportada. Fue aplicado un cuestionario OHIP-14 para evaluar la calidad de vida relacionada a la salud bucal. La exposición a tabaco fue evaluada por dedio de un cuestionario estructurado y validado por medición de los niveles de monóxido de carbono expirado. Pacientes que consiguieron dejar de fumar (NF) fueron comparados con pacientes fumadores que no consiguieron dejar de fumar(F) en relación al OHIP-14. Durante el período de estudio, fueron incluídos 83 pacientes, de los cuales 77 permanecieron hasta el final del estudio. La media de cigarros fumados por día fue de 14,3 y un número medio de años de tabaquismo fue de 29,8 años. Hubo reducción significativa de los escores medios de OHIP-14 en los dos grupos: que dejaron de fumar que no consiguieron de dejar de fumar. Por otro lado, no hubo diferencia entre los grupos en relación a la media de OHIP-14. Dentro de los límites del estudio, concluímos que dejar de fumar no tiene impacto significativo en la calidad de vida relacionada a la salud bucal (AU)

Background: Periodontitis may be associated with the development of head and neck cancer (HNC). A literaturereview was conducted to understand the possible association between them.Material and Methods: Articles published in the PubMed database from January 1999 and May 2020 were re-trieved. Limitations of the studies and biological mechanisms were discussed.Results: A total of 4,232 articles were found. Of these, 13 were analyzed according to inclusion criteria. Most pa-pers found some association between periodontitis and HNC, although differences in periodontal evaluation, sam-ple size, study design and tumor sites were observed. Porphyromonas gingivalis appears to increase the chanceof both diseases, and it may be one of their main potential risk factors. Genetic predisposition is increased byexposure to environmental factors which can directly induce epigenetic changes that contribute to these diseases.Conclusions: Understanding the mechanisms related to periodontitis and HNC has increased, however, well-de-signed clinical studies are needed for better conclusions. Furthermore, the advent of multiple "omic" technologieswill help comprehend their possible association.(AU)
